Question

Use the graph of y = f(x) to graph the given function g.

g(x) = -2f(x). Where f(x) is the solid function and g(x) is the dotted.

Answer 1

the negative sign will reflect the graph of f(x) in the x axis and the 2 will stretch the graph of f(x) parallel to the y axis with factor 2

Answer 2

so which one do you think is correct?

Answer 3

look for the reflection in the x axis first
